WTB: DAS BX-2 or BX-1 skimmer + spare pump

I'm looking to buy a spare pump etc. for my DAS BX-1 skimmer. If anyone has some parts (especially a pump and impeller) or a whole DAS skimmer for sale let me know. This skimmer works great to for me and I'm very happy with it, so I'd like to have parts around just in case. I'd also be really interested in upgrading to a DAS BX-2. If you have any DAS skimmers or parts let me know, thanks.
